Three laboratory clinkers were made with variable C2S content (28-57%), using industrial raw materials. These clinkers were cooled by air and studied by X-Ray Diffraction (XRD). It is concluded that by fast cooling, the active crystal forms of α- and α′-C2S were stabilized in the rich C2S clinker. The hydration phenomena were also studied in cements prepared from these clinkers by DTA-TG and XRD, at 2, 7, 28 and 90 days. The combined water and the liberated Ca(OH)2 were quantitatively determined by means of thermogravimetry and the hydration rate was studied. It is concluded that the hydration rate differs at the early ages, but it progresses with the same rate after 28 days. No significant differences in the formed hydration products of these cements were observed by XRD. © 1990. (EN)
